Do not use image CMD if user gave ENTRYPOINT
This matches Docker behavior, and seems to make sense - the CMD may have been specific to the original entrypoint and probably does not make sense if it was changed. While we're in here, greatly simplify the logic for populating the SpecGen's Command. We create the full command when making the OCI spec, so the client should not be doing any more than setting it to the Command the user passed in, and completely ignoring ENTRYPOINT. Fixes #7115 Signed-off-by: Matthew Heon <mheon@redhat.com>
